Alstroemeria named Stablaco

ABSTRACT

A new variety of alstroemeria plant distinguished by its continuous production of slightly off-white blossoms of medium size, the upper petals of which have longitudinal rows of narrow, dark brown, pencil stripe spots appearing on a yellow background and extending from a pinkish base or flower throat; and by its strong, upright and very rapid growth habit reaching an average height of about two meters.

BACKGROUND OF THE NEW PLANT

My alstroemeria plant originated as a seedling resulting from my crossing of unnamed and unpatented alstroemeria varieties maintained as breeding stock in nursery facilities at Aalsmeer, The Netherlands. I selected this plant for propagation because of its unusual, almost pure white flowers highlighted by the upper petals which have brown pencil stripe streaks extending over a yellow background from a pink throat or base and reproduction was done by me at Aalsmeer by dividing the roots of the discovery plant. Continued propagation of this new plant through successive generations, by dividing root stock, has demonstrated that the novel characteristics of the new plant hold true from generation to generation and appear to be firmly fixed.

DESCRIPTION OF THE DRAWING

This new variety of alstroemeria plant is illustrated by the accompanying photographic drawing which, in full color, shows a branch of the plant in full bloom with both fully opened flowers and buds appearing in the view, the color rendition being as true as it is reasonably possible to obtain by conventional photographic procedures.
